Big Block or Small Block in my 70 Duster
I do not have any pictures on my I-phone, sorry.
With P/B, you'll have clearance issues with the booster and vavle cover. It is simply a pain to get to and install.
You do not have to swap away bars for ride height. Just turn in the adjuster screw in the lower control arm to raise the car up. Though I really suggest swapping bars for a good ride and control for the street.
The /6 bar is a must have for the strip or the thinner "Drag bars" for racing.
